I would like to see some information about the reliability of Yahoo Finance. [18:52, October 1, 2008 Hulagutten]

There's good evidence that not just Yahoo! Finance but CNN Money and other online business news sources cut and paste press releases from firms routinely.
I didn't realize how prevalent that was until I read this startling report on Yahoo! Finance:

"http://finance.yahoo.com/news/thunder-energies-discovers-invisible-terrestrial-000000459.html" "SURREY, British Columbia, Jan. 20, 2016 /PRNewswire/ - Thunder Energies Corp (TNRG:OTC) has recently detected invisible entities in our terrestrial environment with the revolutionary Santilli telescope with concave lenses (Trade Mark and patent pending by Thunder Energies). Thunder Energies Corporation has previously presented confirmations of the apparent existence of antimatter galaxies, antimatter asteroids and antimatter cosmic rays detected in preceding tests. In this breaking news, Thunder Energies presents evidence for the existence of Invisible Terrestrial Entities (ITE) of the dark and bright type.

"This is an exciting discovery. We do not know what these entities are; they're completely invisible to our eyes, our binoculars, or traditional Galileo telescopes, but these objects are fully visible in cameras attached to our Santilli telescope," stated Dr. Ruggero Santilli, CEO Thunder Energies Corp.

You can read a virtually identical report at CNN Money and every other business news outlet that uses PR Newswire as a source of business news:

This may mean we can't just take the online business press's word for anything - two of the most visible large players in business news just showed us they don't actually look at what they put on their Web sites or serve up to would-be investors. They're just megaphones for anyone who can Email press releases. And it means that wikipedia editors ought to view anything in the business press as potentially a WP:PRIMARY source of information, WP:PROMOTION. or both.
This particular report also qualifies as WP:SENSATION churnalism. though it's difficult to say whether there was enough editorial oversight in running these articles to make it purposeful churnalism on the part of Yahoo! Finance or CNN Money - the most parsimonious explanation is sheer carelessness, which is enough to make these two sources not WP:RS.

There is strong evidence that the number of stock irrelevant racist posts challenges, if does not exceed, talk about stock on Yahoo Finance Forums.

Spot checks will reveal whether there is more openly racist posts having nothing to do with stock discussion than there are attempts at even actual stock discussion. For verification, one need only check the pages, for instance, of the yahoo forum set up allegedly for the discussion of facebook stock trading at http://finance.yahoo.com/q?s=Fb over any random number of title pages. Alternatively, simply do google searches for "yahoo finance" and "racism" or variants thereof where reporters of well known publications have investigated the hypothesis of to what extent yahoo finance is a stock discussion forum, on average, or a discussion that on average focuses on other topics protected by the First Amendment. — Preceding unsigned comment added by 24.24.167.222 (talk) 00:02, 6 August 2012 (UTC)

After giving trying to use the link you provided to find these allegedly racist posts, then Google-searching "Yahoo Finance racist".
I found that the articles themselves didn't discuss stock as much as they themselves touched on issues of race.
The first page of that search had these links (other links on that page were either duplicates of links already on the list, or dead):

http://finance.yahoo.com/news/people-calling-sams-club-ceo-174039804.html http://finance.yahoo.com/video/al-sharpton-trump-playing-knows-235020814.html http://finance.yahoo.com/news/peoples-racist-facebook-comments-ending-234400980.html https://finance.yahoo.com/news/15-000-march-helsinki-anti-racism-protest-135618886.html https://finance.yahoo.com/news/black-lives-matter-activists-rio-highlight-racism-190617149.html https://finance.yahoo.com/news/air-china-slammed-racist-magazine-article-london-142926345.html

I read the last article on that list because it only had 22 responses. It was about Air China's apparent cultural insensitivity in warning "London is generally a safe place to travel, however precautions are needed when entering areas mainly populated by Indians, Pakistanis and black people" in its in-flight magazine. The only part of London I personally ever felt uncomfortable in was Soho, but I've had English friends express amazement and shock over the parts of South London I've driven through (this was in 1994) without being bothered by anyone in the least.
Anyway, the posts were a lively give-and-take on the issue, which is what a reasonable person would want to hear. Few of the posts were absolutely politically correct, and some were racist, but not virulently so, more like "yes, the Chinese do think they are the master race" or "well, you don't want to walk alone in some parts of London... ". Someone made the point that the US State Department makes those same points about some areas to would-be overseas travelers, but in a more politically correct fashion.
In any case, part of the problem is that Yahoo! Finance seems to cater to those for whom racial politics is a strong concern. Is it reasonable to expect that there would be no discussion of race in an article that was primarily about race? loupgarous (talk) 01:40, 8 October 2016 (UTC)
